1 all whom it may concern Be it known that I, ANTHONY VANonnmm, acitizen of the United States, and resident of Grand Rapids, in thecounty of Kent and State of Michigan, have, invented certain new andusefnla Improvements in Brush-Making Machines, of which the following,taken in connection with the accompanying drawings, is a specification.

i r ection as Fig. 2. Fig. 4 is an elevation of vi Fig. I.

My invention relates to improvementsin brush making machines and itsobject is to provide a machine of the class shown in my (co-pendingapplication Serial No. 741,834, filed Jan. 13, 1913., with automaticmeans for adjusting a brush blank step by step in the various positionsnecessary to insert tufts of bristles, to automatically stop the machineat a predetermined point in its operation, and to provide the same withvari ous new and useful. features hereinafter more fully described andparticularly pointed out in the claims.

the same as in theco-pending application,

The driving shaft 1 of the machine carries a driving pulley 2 looselythereon which is engaged by a driving friction clutch '3 to connect thesame to the shaft upon operation by bell crank mechanism 4, which isconnected by a'rod 7 to an arm 6 on therocker shaft 5, this shaft beingprovidedwith' a lever 9 which may be operated to thereby hold-theclutch, in engagfment with the ul-- ley to operate the mac ine.- .On theriving shaft are located cams 13, 14 and 15 which operate, respectively,the staple guide,

'the' staple driver and the drill arm.

counter shaft 12 at rightangles to the driving shaft 1 is connectedthereto by miter gears 12 and .is driven by means of-such connection.Cams 16, I7- and18 are located on the counter shaft and operate,respectively, the drill arm in'its horizontal movement, the bristle feedWheel by'means of the reci-procable rod 21, and the staple formingmechanism. I have also shown in this ap-.;. I

plicationfa pulley'99 for-driving the drill,

a staple guide 9.4,two superposedbristle' beds and39 pivoted in brackets88, the bristle feed wheel 87, the air pump 100,the di'es'98, thetransfer finger 93, the fastener 89, the feed rollers -91and operatingplication previously referred to.

To automatically-stop the machine, I proarm (3, which when the lever 9is released will cause the clutch 3 to be thrown out of engagement withthe pulley 2, thereby automatically disconnecting the power'and stoppingthe machine. .When the machine is running, the lever 9 is held in.position to ('n gage the clutch with the driving pulley ride acontractile spring S'connect'edto the by means of a. latch or hook 10,best shown" in Fig. 5, which hook may at any time be manually releasedthrough the liandle 11.: l

The hook is normally heldiirmly in-engagement with lever 9 by a spring11.

As a means to automaticallyv release the lever f) and-stop the machine,I have provided a push rod 29 pivoted at one end to the vertical member22 of a bell crank lever, which is pivoted on a stud 60, the horizontalmember 22 of this lever being connected by rod 20 to an eccentric 19 onthe counter shaft .12, the lever through such connection beingoscillated at each cycle of the machine. Rod 29 is slidably supportedadapted to engage the end of the lever and raise the same, therebylowering the other 'end of lever 30 suflici'ently that push rod 29 mayengage the latch 10 and raise the same, releasing lever 9 and through itthe clutch, and stopping the machine. Cam

drum 65 is rotated step by step by means of a pawl 24 mounted on an arm23 extending from the bell crank 22 and oscillating therewith. Pawl 24extends in opposite directions from its pivot and at the end opposite.the drum engaging end it is pivotally attached to a rod 26, at one endthereof, the other end being provided with a pin 27 slidable in a recess28 in the side of lever 22. A spring 25 interposed between members 22and 26 serves to hold the pin always in contact with member 22.

As a means of limiting the movement of the'drum ,65 to the last. part ofthe movement of the pawl 24, whereby the drum is shifted in proper time,the stroke of the pawl being greater than the spacing of the ratchet 65on the drum, the pawl is lifted to go clear of all but one of theratchet teeth by means of an inclined wedge 27 which engages the in 27and depresses it during a portion. 0 the movement of the pawl,

' raising the pawl clear of the teeth traversed thereby, while the pinis in contact with the incline. a

' In the drum 65 are numerous holes 73 arranged spirally therein toprovidea sutli cientnumber to correspond to the number of tufts ofbristles to be inserted-in the brush blank. The drumis, mounted on alongitudinallymovable shaft 64, which rotates therewith, and a worm 67having a pitch corresponding to the spiral arrangement of the rows ofholes in the drum is fixed in the frame of the machine and looselymounted on the shaft 64. A pawl 68 is fixed on the shaft 64 and rotatestherewith, and it traverses this worm, movingthe shaft longitudinallyand with it the drum whereby the spirally arranged row of holes willpass under a given point as the drum rotates. Pawl 68 is yieldinglyheld. in engagement with the worm by a spring, and is provided with alever-69 having pivotal attachment with respect to the shaft. 64allowing the pawl 68 to be disengaged from the as for instance inputting in alternate rows of white and black bristles, or an outermargin of one kind and an inner portion of another kind, a pin 38 isinserted in the side of the bristle beds and en aged by an arm 37 on arock shaft 36. 'lhe brackets 88 are pivoted nearest to this end of thebeds and the end of the beds next to the feed wheel 87 normally drops toa position adapted to feed bristles from the upper bed. Whenever tuftsare to be fed from the lower bed, screws 74 are inserted in suitableholes 73 corresponding to these tufts when the machine operates, andeach of these screws engages one arm 35 of a bell crank lever and raisesthe same, the other arm of which projects upward and supports a hook 31having a shoulder 31 adapted to engage a projection on an arm 32 on therock shaft 36. \Vhenever the arm 33 is moved from under hook 31 byreason of one of the screws 74, the shoulder 31 will engage and move thelever 32 and depress the rear end of the bristle beds and raise the endof the bristles into the feed wheel 87.

arrangement any number of tufts in any part of the blank can be fed fromthe lower bed by inserting screws in the proper holes in the drumcorresponding to the desired openings in the blank to be supplied withtufts of bristle? The brush blank 40 is securely clamped to a bed plate41 mounted on a frame 42 vertically slidable on a bar -13 pivoted at 44on a horizontal axis and swinging within a yoke 45 journaled in bearings46 to turn on a horizontal axis at right angles to the axis 44. The bedaccordingly has an oscillating movement about two horizontal axes atright angles to each other, and also a vertical movement. Theoscillating movement about the axis H-is effected by means of a rod 50longitudinally slidable in the axis l? of the yoke 45 and attached tothe rocker bar by a connecting-rod 51. This slidable rod 50 is providedat its outer end with a grooved'eollar 52 engaged by a bell crank lever53 operated by'a rod 55 connected to the same and extendingdownward thelower end thereof inine the position of the frame 42, it is lessees 7provided at its lower end with 22 supporting rnit the com drum to bereturned to starting position, the arms 56 end 57ers prolongedoppositely from the stud59 end engaged by e litti g; cam 61 mounted on erotating shaft 62, the opposite end of which is provided with a manuallyoperated crenk 63. -And to properly locetethe drum for startingposition, e stop 78 is provided consisting of a. rod sliclebly mountedin a side of the frame of the machine, and normally drown inwsrdly underthe influence of spring 79 so that collar 80 mounted on the rod contactsagainst the side of the frame, such rod, how

such position that the drnn'i is placed in proper starting position. Toautomatically return the drum, n. splrel spring 66 stir-- rounds theshaft or and engages s'coller 86, whereby when the pawl 68 is released,the shaft 64 is moved endwise to starting position. To hold the'druinfrom turning except as moved by the pawl 24. o. friction brnlre 70 isprovided which is bifurcated and clemped by a bolt through the some onthe hub of the drum and provided with an arm 71 slidably engaging a stoppin 72, The drum can turn only against the friction of the brake andaccordingly is not open to accidental movement except underextraordinnry circumstances. Yoke 45 is iournaled on a verticallymovable frame Sl sdjnsted by it screw 82, provided with e'hand wheel 83geared thereto.

The form 5 is carried on a slide 8 lverti- I .cally adjustable on theframe 81 and adjusted by a screw provided with who-11d wheel 86. v

The ca-m drum 65 is provided with holes 73 corresponding in number tothe number of tufts to be setin the brush to be made on the machine.Screws 74- or equivalent projccting niei'nbers are inserted in asinany'of these holes as correspond to the tufts required to be set inbristles from the lower bed. In e. hole counting from thcfirst orstarting hole, corres )ondin'g to the next after the last tuft to e set,{i stop pin 75 is inserted which operates to stop the inz chine when thework 1S completed.

During short thenext corresponding operation, the pswl 24cshifts the coin drum one notch of the ratchet, which movement" shiftsthe brush blank to proper position for the next tuft of bristles, theblank beingmoved about through the levers 57 and 5-7 the rod 58 end arm59, endshifting the blenlt properly to space apart the tufts in therespectiverows; and, at the end of each rowthe corn '7! slides the shaft50 longitudinally snlliciently to ll to pro-perlyspace apart therespective wows ct bristles. It will be noted-that in Fig. 2 there arepoints in the cam 77 where an abrupt change inthe surface of the coin isshown, these changes being of smell dothat, the shifting of the blank toset another row of bristles occurs; and at'thc abrupt drop ofconsiderable degree shown, the brush is finished, and the blanlt'enclholder swung over to the original or starting row. In the meantime theform 54- supports the blank in proper elevation to determine the depthat which the bristles are to be inserted in the blank. By changing theoutline of said cams and form, the machine may be utilized to. makevarious forms of brushes.
